01
Financial claims
Pause if savings are guaranteed, energy-price assumptions are hidden, export is treated as fixed, or a long payback is presented without equipment replacement or degradation assumptions.
02
Sales behaviour
Be cautious with countdown discounts, claims that a grant expires today, demands for immediate deposits, invented scarcity or reluctance to let you compare paperwork.
03
Evidence gaps
Missing equipment models, vague warranties, unexplained subcontracting, unitemised scope and verbal-only promises should be resolved before signing.
